A heat exchanger, operating under counter current flow, made of two concentric

A heat exchanger, operating under counter current flow, made of two concentric tubes is used to cool a soup. The soup soup is 9800 kg/h and specific heat of the soup is 2500 J/kg.K. The mass flow rate of water is 8000 cooled from 85 C to 55 C by water entering at 25 C. The mass flow rate of the kg/h and specific heat of water is 4180 J/kg.K. Determine the heat exchanger area and heat transfer rate for an overall heat transfer coefficient of 270 W/m.
